  • Compact, lightweight design for accurate measurements anywhere!
  • Reliable measurements, guaranteed! Precalibrated to NIST-traceable standards
  • Heavy-duty construction protects against knocks and jars
  • ±2% basic RH accuracy
The Digi-Sense professional thermohygrometer provides accurate and reliable readings in an ergonomic handheld design. Ideal for use in laboratories, cleanrooms, warehouses, factories, and storage areas. Plus the NIST-traceable precalibration means you get reliable measurements right out of the box, saving you time and money!

Double-molded heavy-duty housing provides superior protection and is ideal for tough applications. This meter provides measurements in humidity, dew point, wet bulb, and temperature. The meter can also measure in absolute humidity grains per cubic feet or per cubic meters. View measurements in low light areas with large triple digit backlit display. Meters feature Min/Max and Hold functions, user-selectable temperature readout in °F or °C, integrated humidity and temperature (NTC thermistor) sensor, and auto power-off.

A digital hygrometer, also known as thermohygrometer, measures and simultaneously displays temperature and humidity measurements. Davis Instruments offers a digital hygrometer among the many other meters it features in its online and print catalog. Meters are available with integral probes or remote probes, depending on your application. For measurements that are convenient and easy-to-reach, select a meter with an integral probe that allows one-handed operation. When measurements are necessary in hard-to reach areas, meters with remote probes provide access, as well as, easy display readability. Select from thermohygrometers that offer features such as data hold, min/max, data logging, infrared temperature measurements, RS232 output, printing capabilities, selectable temperature units and many other features. Humidity sensors provide high level of accuracy and ability to be calibrated for continued accuracy and stability. Sensor calibration is available through our in-house calibration lab, InnoCal, or available calibration salts. Thermohygrometers are ideal for use in HVAC, IAQ and other environmental industries, and industrial applications. If you have questions about a digital hygrometer contact a Davis Application Specialist today.

  • Q:

    We have a NVLAP ISO17025 calibration lab for calibration of our equipment. Can you provide the method to make adjustments to the model 20250-21 thermo-hygrometer
    Asked on 5/5/2016 by Fred from Aiken SC

    1 answer



      For ISO 17025 calibration we recommend sending the unit into our in house calibration lab using calibration part number 17030-20.
